What is L-Glutamine?
L-Glutamine is an amino acid, one of the building blocks of protein, and much of it is produced in our muscles. While it is the most abundant amino acid in the blood, there are times when our body's need for L-Glutamine outpaces our ability to make it, usually during periods of intense physical stress.
What does the research say about L-Glutamine?
L-Glutamine plays a particularly important role in the gut. It is the main energy source and nutrient for the cells that line the walls of our intestinal tract. This is why researchers have looked at its role in the intestinal barrier, the lining that controls what passes from the gut into the rest of the body.
The gut and the immune system are closely linked. Many of our body's immune cells are found in the gastrointestinal tract, and they use L-Glutamine as a fuel too. Researchers have studied glutamine as an 'immunonutrient', especially in times of illness or injury, when the body's demand for it rises.
